EMERGENCY VALVE.

Application filed September 24, 1924. Serial No. 739,575.

To all whom it may concern:

Be it known that I, ANDREW M. MORRISON, a citizen of the United States, and a resident of the city of Dubuque, in the county of Duthe accompanying drawings, and to the numorals ,of reference marked thereon, which 7 form a part of this specification.

This invention relates to emergency valves and niore particularly to those usedin connection with oil filling lines. In oil filling systems it is desirable to have a valve situ ated in the outlet adjacent the supply compartmcnt as a preventive against loss of asoline or oil, in the event of damage to the aucets' or iping. This is particularly desirable in t e case of oil trucks where the piping and faucets are subject to rough usage and damage thereto might result in a serious loss of oil.

It is therefore an object of this invention to provide a valve which may be inserted in the outlet of the supply compartment which may be closed from a ositions as from the ucket box. I

It is further an object of this invention to rovide a valve for this purpose which may be manufactured so that it is adapted toconform to the various requirements as to right hand or left hand control as found necessary upon installation. It is also an important object of this invention to provide a valve of this class in which the seat comprises a composition disc secured between a collar integral with the stem and a nut threaded thereto.

It is also an object ofthis invention to prolurality of remote rivers seat or the vide in a device of this kind a means for. changing the control from the right-hand to the left-hand side of the valve.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawings.

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings: Figure 1 is a front elevational view partly in section of the device installed in a supply compartment outlet.

Figure 2 is a side view of the device.

Figure 3 is a cross section of the device,

along the line 3-3 of Figure 1.

As shown on the drawings:

The numeral 1 refers to a valve casing which is threaded in a flange member 2, the latter being riveted or suitably secured in a bottom 3 of a supp-1y compartment 4. The bottom 3 is apertured at 5 to receive the casing 1; an end of which extends into the compartment 4. The end of the casing 1 extending into the compartment 4 is internally threaded to receive a cap member 6 and contains slots 7 in the sides thereof for receiving oil from the compartment into said casing. The cap member 6 is apertured at the to thereof to form a guide for the upper en of a valve stem 8. The cap member 6 is counterbored at the bottom to receive a spring 9 which surrounds the valve stem 8 and bears downwardly u on a collar 10 integral with said stem. ecured beneath the collar 10 on the stem 8 is a disc member 11 which is preferably of composition material. The disc 11 is threaded to the stem 8 and is locked thereon beneath the collar 16 oppositely disposed to the member 15 is apertured to receive the other end of the shaft 14 and is also threaded to-enga e in the casing 1. A packing ring 17 an a washer 18 pressed by the member one end of the shaft 14. The member p against a collar 19 integral with the shaft 1 prevents the oil leaking through said memher along said shaft 14. An arm 20 is mounted against rotation on the outer end of the shaft 14 and is actuated b a suit-' able rod 21 connected to a suita le lever (not shown) located in any desired position from which it is desired to actuate the valve.

Threaded to the lower end of the valve cas- 1 ing is an outlet pipe 22.

In the o eration of the valve which is lo-- cated in t e outlet to the supply compartment 4, the lever (not shown) connected to the rod 21 in a remote position such as the bucket box is actuated to raise the valve disc 11 from its seat. This allows oil toflow from the compartment 4 through the valve casing 1 into the outlet pipe 22 to the faucets in the bucket box. If something happens to the It is frequently necessary in order to acecommodate various positions in the outlet lines relative to the operating positions that some of the valves be actuated from the right-hand as well as the left hand or viceversa. It will be seen that the supporting members '15 and 16 and the position of the shaft 14 and the arm 20 may be changed so that said arm 20 is on the left-hand side of the casing instead of the right-hand side, as

shown in the drawings.

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range Without departing from the principles of this invention, and I therefore do not purpose subscribing witnesses.

limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my inventlonz A valve for the urpose described comprising an elongated hollow casing, an exterior threaded portion intermediate the ends of said casing, a valve seat within said casing, said casing having slots in the side thereof above said seat, a cap member closing one end of said casing, said cap hav-- ing an aperture, a valve stem slidable in said casing and aperture, a valve disc secured on said stem and adapted to fit said seat, a

spring surrounding said stem one end of said spring engaging said cap, the other end abutting said disc, the other end of said cas-' ing being connected to a pipe, said casing being provided with a pair of transverse apertures for supporting a means for actuat-' ing said valve stem and interchangeable bearing members mounted in said apertures. In testimony whereof I have hereunto subscribed my name in the ANDREW M. MORRISON.
